Aerosol provision device comprising a radio frequency receiver for power harvesting

Abstract

A method comprising: receiving radio frequency signals using an antenna; extracting (e.g. using a power module) electrical power from the received radio frequency signals; and controlling (e.g. using a control module)) use of the extracted electrical power by a vaporiser of the aerosol provision device.

1 . A device comprising:
 an antenna configured to receive radio frequency signals;   a power module configured to extract electrical power from the received radio frequency signals; and   a control module configured to control use of the extracted electrical power by a vaporiser of the aerosol provision device.   
     
     
         2 . A device as claimed in  claim 1 , further comprising a reservoir, wherein the reservoir is configured to store a liquid or gel and the vaporiser is configured to vaporise the liquid or gel. 
     
     
         3 . A device as claimed in  claim 1 , wherein the vaporiser is powered directly by the extracted electrical power under the control of the control module. 
     
     
         4 . A device as claimed in  claim 1 , further comprising a power storage device for storing electrical power extracted from the received radio frequency signals by the power module. 
     
     
         5 . A device as claimed in  claim 4 , wherein the vaporiser is powered, at least in part, by the extracted electrical power stored in the power storage device. 
     
     
         6 . A device as claimed in  claim 4 , wherein the power storage device is a battery or a supercapacitor. 
     
     
         7 . A device as claimed in  claim 4 , wherein a capacity of the power storage device is limited such that the power storage device is configured to store sufficient energy for a single use or puff of said aerosol provision device. 
     
     
         8 . A device as claimed in  claim 4 , wherein the control module is configured to control use of the extracted electrical power for charging the power storage device. 
     
     
         9 . A device as claimed in  claim 4 , wherein the control module is configured to simultaneously charge the power storage device and to provide electrical power to the vaporiser. 
     
     
         10 . A device as claimed in  claim 4 , wherein the control module is configured to preferentially provide electrical power to the vaporiser over charging the power storage device. 
     
     
         11 . A device as claimed in  claim 1 , further comprising said vaporiser. 
     
     
         12 . A device as claimed in  claim 1 , wherein the antenna is configured to transmit and/or receive data. 
     
     
         13 . A method comprising:
 receiving radio frequency signals using an antenna;   extracting electrical power from the received radio frequency signals; and   controlling use of the extracted electrical power by a vaporiser of the aerosol provision device.   
     
     
         14 . A method as claimed in  claim 13 , further comprising vaporising a liquid or gel stored in a reservoir. 
     
     
         15 . A method as claimed in  claim 13 , further comprising powering the vaporiser directly by the extracted electrical power. 
     
     
         16 . A method as claimed in  claim 13 , further comprising storing electrical power extracted from the received radio frequency signals. 
     
     
         17 . A method as claimed in  claim 16 , wherein the vaporiser is powered, at least in part, by the extracted electrical power stored in the power storage device. 
     
     
         18 . A method as claimed in  claim 16 , further comprising simultaneously storing electrical power and providing electrical power to the vaporiser. 
     
     
         19 . A method as claimed in  claim 16 , further comprising preferentially providing electrical power to the vaporiser over charging the power storage device.
